>Is it though?

Absolutely!

In order to learn/study something, you need unbounded enthusiasm/motivation (though it maybe irrational). Once you have jumped in with both feet, reality will slowly strip the fantasies but hopefully by that time, one's interest is sufficiently solidified that one can settle down to the long grinding road to mastery. It is Emotion which drives one to Action while Rationality modulates it.

The key is to light the fire within one's imagination. Any kindling will do whether sane or not. Everything that the Human Species has achieved has started from here.

PS: For example, Ramanujan himself used to say that the goddess "Namakkal" revealed the theorems to him!
